Ravi, I just saw that you worked with Professor Jeff Dahn, that is fantastic! I have very high respect on his work on the NMC chemistry!
Love the video, but yes please look into making a larger controller than the 8K and something larger than 855 but smaller footprint then 2000.
Very interesting interview from Zen with Martin! thanks that is amazing to have Martin sharing ALOT info to help people to understand how an excellent company need to work!
Best controllers!
Lookin good Martin ! Nice Haircut 😆
I've met Martin...what a dick!
The problem with the original manufacturer (ASI) locking stuff down to where only the Systems integrator (Grin tech in this case) can help, is that when the SI can't / won't help, you're screwed. I have a Phaserunner (similar to BAC855 I think), with a grin supplied motor / wheel build on a common 52v (14s) battery. I kept getting IPOC (instantaneous phase over current) faults on the controller, only during regen braking, and only under certain circumstances. Grin ultimately couldn't help, and two years later I'm left with a bandaid fix of massively limiting regen phase amps to compensate. Even with this bandaid fix, to this day, when regen switches from sensorless to sensored control I'll sometimes get what feels like a loss of phase timing and the motor will start to growl. At least it doesn't trigger IPOC and require a power cycle though. To be fair, I'm not blaming ASI, as the PR is a Grin product. But when the systems integrator can't help you, the end user should have access to the tools to investigate further. To me, this is part of right to repair. If you've gone through channels, and still have no resolution, you should have the tools available to try yourself. This 'security' through 'lockdown' rings very much of apple. And to be fair, that's NOT a compliment.
Fardriver is cheaper more powerful less expensive and basically android..ASI is apples little brother with tons of restrictions and high price..no thanks!!.
Could you please repeat that?
I have an ASI BAC2000 brand new controller, when I connect it to my CYC BAC app through a Bluetooth connection to upload .xml local file after it connected, I can see the an error message such as: "Error write to controller(22), The operation has timed out." I do not know why do I get this error message for this quality controllers. However, I send multiple email to ASI team for any help as the manufacturer of this controller but they replied that they can do nothing for this issue and just want to get rid of us!
EVERY controller on the planet and literally billions of other devices are built similarly with many tiny SMD components. HOW is this something special or unique to ASI? ASI is a ROYAL PAIN IN THE ASS to work with!!! Can't imagine ever buying their products!
🤣 now try Sevcon!!!
@@Doctorbasss LOL! Right! Already did and totally agree that SEVCON is also a PITA.
Fardriver FTW
@@darkchild256 Are you claiming that the company Far Driver is a PITA? That's true for ASI. They as a company make it quite difficult to work with them. As far as controller setup is concerned, anything FOC will be more complex to set up than something that is not FOC. If you are posting "For the win" because Fardriver isn't FOC and is therefore much easier to set up, well I'd have to point out that isn't really a win at all, jsut an easier setup. I have seen no evidence that Fardriver supports FOC and that explains the much simpler setup...and that is definitely NOT a win when you want best case motor control!
@@de-bodgery Almost didn't recognize you, Fardriver claims FOC and im 50/50 based off of my testing. They are a win for power to footprint ratio in my book. App is relatively useable which is more than you can say for most of the other heavy hitters out there. You rig it up, run auto learn, change e few motor parameters and you are rolling. As you and I have discussed previously on the comment section of one of your vids, Vesc will probably be the DIY savior. For now though, Fardriver does a really great job for my use at 26kw daily driven. Running 96v at 300 amps and it barely-almost never gets above 60C. TBH foot print is about the same vs the 600 and max current is close with the info I could find.
When it comes to having FOC vs not having it, what are the real world efficiency differences, and is it worth it for 1.5-3x the cost depending on what kit you buy? I understand how some with an electrical engineering background want to long for, buy, and build the best, but you'd spend $1500 on a controller for an aluminum pedal bike frame? Why not a bigger motor? Why not a custom welded aerospace grade titanium frame for maximum effectiveness? Its because of the 80/20 rule. Arguably Fardriver is closer to 80/20 for their voltage ranges, current capacity, and app tweaking capability than anything else on the market. If you want to make better cleaner power outside of them, its honestly a high voltage vesc, which there still arent many of. Everything else below is YYK square wave and otherwise. So again I say Fardriver FTW. BAC can find a way to allow some tweaking without compromising their IP, and I hope they do.
Full disclosure though bro, Ive never owned a BAC, but ive done extensive research in my years of building and running my setups. All signs point to VESC taking the market in the near future, and it probably wont be a north or south american who gets to market first with a low cost option.
Anyone here willing to share what they know about the best controller upgrade, based on the best E-Bike for your money in the market right now for only 1100.00
It's only weakness is a 750 Watt Hub Motor, but you get a 30 AMP battery and the brand has several good reviews of it on CZcams, so it's not crap, but I'm torn between getting
this model which might not have enough power, VS having to spend almost 400.00 more to get a 35 AMP model but with a 2000 Watt motor for , less than 1400.00, but it's biggest weakness
is that, they're based out of China with no local storefront for easier assistance if something mechanical breaks down.
The controllers are great, but their lockdown and no end user access is irritating to massive degree. Why do I have to hack and pirate my own BACDoor to modify even trivial stuff in the device I own?
I would say re-watch the video.. you will better understand
I agree! You shouldn't! You should HAVE ready access to all programming of the controller. The programming software is clunky as hell, but not that hard to learn. AS someone that has owned an ASI controller and then taught myself HOW to program one, I'm betting that most people than can handle setting up a VESC can handle programming an ASI controller just as easily! This is far from rocket science and the whole "Hide the setup from the end users" is bull shit!
@@Doctorbasss 10,000 percent disagree! I already understand programming ASI controllers! This is NOT hard! ASI is just being control freaks!
Too expensive
I have two Rad bikes, in less then 1 year and about 235 miles I have gone through 3 controllers. These controllers are ASI controllers model BAC355 TTL. This problem is not unique to me as FB is full of disgruntled consumers whose RAD controllers are failing. Not all that great of a product I'd say!!
Time to tackle some EV industry standards ? @18:50 so we can begin all pulling in a similar general direction like a "civilized" society hmmm? Also, for the record, and pardon my french but, fuck capitalism! #ResourceBasedEconomy
The 'lockout' is exactly why everyone else is using a Sabvoton or a Fardriver. U really think people are gonna buy this controller for a higher price to deal with stupid issues. If I buy a Bugatti it better be 'unlocked' lmao! What a waste. 🗑 🚮
I bought this device.. then struggled to get the tiny cables connected.. didnt know how to set it up.. it doesnt show up in the phaserunner suit. it just says connected but nothing is changable.. I now sell it for 200 bugs .
